Science for the Public presents Dr. Jonathan P. Wilson, California Institute of Technology, Division of Geological and Planetary Sciences, at the Boston Public Library on Boylston Street in a free lecture on Tuesday, November 17 beginning at 6:30 pm.
A nature walk in New England 300 million years ago would have looked quite different from one near Boston today. Instead of forests composed of oaks, maples, and pines, the area would have been dominated by unusual extinct forms: mostly climbing ferns and seed plants under a canopy of trees that more closely resemble telephone poles than anything in a modern garden. How did these plants work?
In this talk, he will explore how recent advances in plant physiology allow paleontologists to understand, in a quantitative fashion, how extinct plants functioned. Are there fundamental physiological differences between extinct plants and living ones? What can we learn about ancient environments and ecosystems from looking at fossil plants?

The Arnold Arboretum is sponsoring a two session class on Saturday mornings, November 21 and December 5, beginning at 9:30 a.m., with Arborist Kyle Stephens. This class will provide an overview of the information necessary to identify deciduous trees during their dormant season. Looking at specific character combinations, participants will learn to determine the genus and species of several types of trees in the Boston area. The group will begin indoors with a discussion of basic classification techniques and then go outside to the Arboretum grounds to explore maples, oaks, lindens, buckeyes, hickories, hornbeams and as many other trees as time will allow. This class is recommended for the beginner-to-intermediate tree observer. The first class meets at the Dana Greenhouse Classroom. The second class meets at the Hunnewell Building. Dress warmly for spending the morning outdoors. A hand lens may be helpful, but is not necessary. Fee $65 Arboretum member, $75 nonmember. To register, log on to www.arboretum.harvard.edu.
